Dilatitibialis wendy Canepari and Gordon , new species Description . Male holotype . Length 3.4 mm , width 2.7 mm ; body elongate, convex. Dorsal surface with head alutaceous, weakly shiny, pronotum weakly alutaceous, shiny, elytron smooth, shiny. Color black except head yellow, pronotum with black basomedian macula extended 4/5 distance to anterior margin, apex of macula weakly emarginate with yellow medially; elytron with 5 small, yellow spots arranged in rows of 2 each plus apical spot ( Fig. 212 ); ventral surface with antenna, mouthparts, prothoracic hypomeron, and legs yellow; abdomen yellowish brown with lateral 1/4 and ventrites 5-6 slightly paler. Head punctures small, separated by a diameter or less, each puncture about as large as 2 eye facets; pronotal punctures slightly larger than head punctures, separated by 1 to 2 times a diameter; elytral punctures larger than those on pronotum, separated by 1 to 3 times a diameter; metaventral punctures larger than those on elytron medially, separated by 1 to 2 times a diameter, coarser and separated by less than a diameter toward lateral margin. Clypeus deeply emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 6 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin rounded, basal margin with trace of bordering line medially. Epipleuron narrow, grooved, descending externally, deeply emarginate for reception of femoral apices. Protibia widely flanged, flange slightly wider than remainder of protibia, outer margin nearly straight, smooth, sponda distinctly extended beyond protibial flange. Carinae on prosternal process widely separated at apex, convergent toward base, joined at basal 1/4 with single carina extended to basal margin of prosternum. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with primary pores laterally between ventrites 4-5 large, extended under apical 1/3 of 4th ventrite; postcoxal line on basal abdominal ventrite slightly flattened along posterior ventrite margin, extended forward, ventrite with sparse, short pubescence and large, dense punctures; ventrites 2-4 pubescent throughout, punctures large, becoming denser toward lateral margin; 5th ventrite coarsely, densely punctured in basal 2/3, apical 1/3 depressed, feebly depressed by primary pore laterally, without tubercle on each side of middle, apical margin broadly, weakly emarginate; 6th ventrite short, narrow, depressed medially, apical margin weakly emarginate, sparsely pubescent on each side of median depression, lateral angle abruptly rounded, surface densely punctured. Apical tergite with apex slightly convex. Genitalia with basal lobe slender, 3/4 as long as paramere, asymmetrical, sides parallel, apex obliquely truncate; paramere wide, curved, Psc , apex with small, ventral projection ( Fig. 213, 214 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm short, wide, apex rounded, outer arm short, wide, longer than inner arm, with accessory piece, basal border broadly, weakly emarginate ( Fig. 215, 216 ). Female . Similar to male except head black, pronotum with median macula extended to anterior pronotal margin. Genitalia with spermathecal capsule, short, wide, widened from base to broad cornu; bursal cap without sclerotized arms, apical strut short, narrow ( Fig. 217 ). Variation . Length 3.3 to 3.5 mm , width 2.4 to 2.7 mm . Elytral spots may be slightly larger or smaller than on the holotype . Type material.
